Thunderstorm black filled icon

About the Thunderstorm black filled icon

A single billowing cloud with three rounded humps sits above a tall zigzag lightning bolt that starts inside the cloud body and stabs down past its base. The bolt dominates the lower half, so the icon reads as an active electrical storm rather than plain rain. Use it in weather apps and forecast strips, severe weather alerts, aviation and sailing dashboards, power outage notices, and energy or high-voltage presentations.

The bolt is drawn in open outline with a wide angular kink, cutting through the cloud's bottom edge so the two shapes interlock instead of merely stacking. Cloud curves stay soft against the sharp bolt for contrast. Pair it with rain, snow, sun and wind icons for a complete forecast row; it holds up well down to 16 px.

This is the solid black filled version of the thunderstorm icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
